Due to the coronavirus pandemic, Pope Francis’ liturgies for Holy Week and Easter, which usually include the presence of thousands of people, will be held without public attendance this year.

According to an online notice from the Prefecture of the Papal Household, “because of the current global public health emergency, all the Liturgical Celebrations of Holy Week will take place without the physical presence of the faithful.”
